Topic: Formula handling Nulls? Posted: 08 Jul 2016 at 9:30am
Currently have the following formula:
if {Address.SubUnitTypeId} = 0 or IsNull({Address.SubUnitTypeId}) or IsNull({Address.SubUnit}) or IsNull({AddressSubUnit.Description}) then {Address.StreetOne} else if {Address.SubUnitTypeId} <> 0 then {Address.StreetOne} + ' ' + {@SubUnit}
however when the Nulls are True, it is NOT showing the Address.StreetOne I am unsure why?

the NULL has to always be the first condition so in your first two conditions
"if {Address.SubUnitTypeId} = 0 or IsNull({Address.SubUnitTypeId})"
it hits the null and evaluates for = 0 first and then stops because it it does not know how to handle the null.
I find it easier to just use the option in the formula editor to 'use default values for nulls' then you can just use the "<> 0" or "= 0"
